Background
Along with the continuous development and progress of human society, the problems caused by vibration are more and more extensive, the quantity of the vibration generated in production and living of people is increased day by day, the life of people is influenced constantly, and a plurality of buildings with extremely high cultural historical value and great humanistic significance in China are threatened. Particularly, vibration caused by building or road construction and traffic vibration is vibration which is propagated from a vibration source to four places, and is elastic wave radiated to the periphery from the vibration source. The wave propagation method can be divided into three types, namely longitudinal waves (P waves), transverse waves (S waves) (both the longitudinal waves and the transverse waves belong to body waves) and surface waves (L waves).
The damage of the vibration to the building is found in the following three points: the transverse wave causes the horizontal swing of the building, which causes the damage of the building and has great destructive power. The method is equivalent to applying repeated action force in the horizontal direction to a house building, and when the magnitude and the caused deformation exceed the limit of the vibration resistance of a building beam structure, the whole building can be inclined or toppled to cause damage; the longitudinal wave makes the building produce jolt from top to bottom, because some buildings are long in the past, its vertical stability is relatively poor, when the vibration is great, can make the bottom increase very big dynamic load as load-carrying members' post in the twinkling of an eye, the dead weight on stack upper portion, when surpassing bottom post bearing capacity, thereby the bottom post can collapse and lead to destroying. 3. The buildings are affected by foundation soil disturbance generated by surrounding vibration sources and low-frequency and micro-vibration actions for a long time, and the buildings can generate permanent and irreversible fatigue damage, so that the safety of the buildings is obviously reduced, and various diseases occur.

Current barrier vibration isolation is largely divided into two broad categories, namely continuous vibration isolation barriers and discontinuous barriers. The continuous vibration isolation barrier is typically represented by a vibration isolation trench, when an artificial vibration source with higher vibration frequency and earthquake vibration are performed, the properly designed vibration isolation trench can play a good vibration isolation effect, but part of vibration sources with lower vibration frequency have generally longer wavelength, if the hollow trench is selected as the vibration isolation barrier, the hollow trench is required to have great depth, the requirement has great operation difficulty in actual construction, if a continuous wall is selected as the vibration isolation barrier, a very large engineering quantity can be generated, the construction cost is greatly improved, and particularly, when the geological conditions of a construction site are very poor, the construction difficulty and the construction cost can be greatly improved. The foam concrete, also called foam concrete, is to add chemical foaming agent or physical foaming agent into slurry made of gelled material, admixture, modifier, brine, etc. after foaming, through mixing and stirring, pouring and forming, natural curing forms a new light material containing a large amount of closed air holes, its material selection is convenient, the manufacturing cost is low, and the foam concrete block made of fly ash, sand, stone powder, tailings, building rubbish, calcium carbide powder as the main raw materials, its technical performance meets the national standard requirement of "foam concrete block"; and the foam concrete block is a porous material and has low elastic modulus, so that the foam concrete block has good absorption and dispersion effects on shock impact load and can consume the energy of vibration waves in the vibration propagation process.
